BINDER.

SPECIFICATION forming part of Letters Patent No.434,160, dated August12, 1890.

Application filed May 21, 1890. Serial No. 352,587. (No model.)

Fig. 2 is a plan view of the binding mechan ism removed from the covers;Fig. 3, a crosssection on line 3 of Fig. 2, looking in the direction ofthe arrows; and Fig. 4 a similar section illustrating a modification.

A A are the covers of the binder; B, the back; C, the fixed portion ofthe binder; D, the binding-arm, and E a lock or catch.

The covers and back of a binder embodying my improvements are made ofcanvas or other suitable material, the covers being preferably stifienedin any suitable manner, as by means of card-board. To the back issecured the fixed part C of the binding mechanism. As shown in Figs. 1,2, and 3, this con sists of a piece of sheet metal of any properdimensions bent over upon itself longitudinally and having its edges 0 cthen bent inward toward the back and inclining toward each other, asshown in Fig. 3, thus forming a substantially triangular opening alongone side. I next make the binding-arm D. This consists, preferably, of asolid strip of wood, metal, or other material, of any suitable length,of a substantially triangular cross-section, and having its sidespreferably slightly hollowed out, as shown in Fig. 3. This arm ispivoted between the edges of the part C, at a point near one endthereof, and with its thinner edge turned toward the opening between theedges 0 0, so that as the arm is swung inward toward the part C theseedges may engage with the beveled sides of the arm and bind or pressagainst the same. To hold the arm in place, I prefer to provide aspring-catch E, adapted to lock over the end of the arm, as shown. meansfor accomplishing this purpose may be used instead of this catch, asdesired.

I have so far described the device as comprising a hollow resilientmetallic fixed piece and a solid arm pivoted therein and adapted toengage with and be bound between the elastic springing edges thereof. InFig. 4this arrangement is reversed, the fixed piece being made solid ofwood or other suitable ma-- terial, provided with a longitudinal opening0, and the binding-arm of sheet metal or other resilient materialadapted to enter the opening 0 and be bound and held therein by itsresiliency. If desired, both parts may be made of sheet metal or otherresilient material, or both solid, this being but a change of materialand form and wholly within the spirit of my invention.

In using the binder the catch E is drawn back and the arm D turned outof the way. The sheets to be bound are then inserted into the opening 0between the edges of the piece C, and the arm being swung around intothe opening and caught by the catchE binds the sheets between its outeredge and the edge of the piece C and holds them firmly in place.

I claim 1. A binder comprising the covers A A,a piece C, attachedthereto, having a substantially triangular opening 0 along one edge, abinding-arm D, of a substantially triangular cross-section, pivotallyattached to the piece C and adapted to engage with the opening 0, andmeans for holding such arm in place, substantially as described.

2. A binder comprising the covers A A, a piece C, of resilient material,attached thereto, having its edges bent so as to form a substantiallytriangular opening 0, a solid bindingarm D, pivot-ed in the piece C andadapted to enter the opening a therein and be bound between the elasticedges 0 0 thereof, and a spring-catch E to hold the arm in place,substantially as described.
